The low-cost, compact, lightweight 20/20ML-1 UV/IR Flame Detector comprises UV and IR sensors that detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, and metal and inorganic fires up to 15 metres.

The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.

A compact-style detector featuring excellent detection sensitivity. The UV/IR flame detector senses energy in the short-wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The IR sensor is sensitive to radiation over the range of 2.5 to 3.0 microns. The signals from both sensors are analysed for frequency, intensity and duration.
